This article describes Participatory Training Evaluation Method (PATEM) of measuring participants' reaction to the training. PATEM provides rich information; allows to document evaluation findings; becomes organic part of the training that helps participants process their experience individually and as a group; makes sense to participants; is an interesting and exciting group activity; becomes a part of the learning process; is flexible enough to accommodate what are often dynamic and less-than-predictable training contexts; and can be used in groups of various sizes. The article includes step-by-step instructions on how to use PATEM and illustrative examples of participants' feedback. (Contains 4 tables.)
